In early season five, during Scully's resurrection and Mulder's crisis of faith, they travel to small-town Nebraska to investigate a series of portentous crop circles and end up plumbing the mysteries of the human heart.

It's Star Trek's 50th anniversary and Sheldon organizes a commemorative role-playing mission. Can Amy and her alter-ego Nurse Chapel discover what's hiding down in engineering, save the Enterprise, and win over her Vulcan man? Shamy, of course, but the whole crew is on board. One-shot. CANON.

Thanks to a closeness developed in the wake of Leonard's departure, Amy feels confident about the current trajectory of her relationship with Sheldon Cooper. However, one overheard conversation is all it takes to set in motion a series of events that will either destroy the relationship she once revered or catapult it to heights she's never allowed herself to dream possible.

Sheldon embarks on an emotional journey, to finally find out why he can't be physical with Amy. He resorts to methods that might be effective, and may or may not change his and Amy's relationship for the better, but it might also change the way he views himself. Shamy.
